Service - 22

9.  To adjust the front of the deck, loosen the cross 

bolts (B) in the carrier frame.  

B

Move the bolts forward in the slots to lower the 

deck or move the bolts rearward in the slots to 

raise the deck. 

Note: 

slight movement of the bolt 

in the front carrier slots will make a significant 

difference in the front deck height.

10. After deck has been leveled, make sure the 

cross bolts in the carrier frame have been tight-

ened and the nuts on the rear height adjustment 

links have been locked against the rod ends.

Tire Pressure

Tire pressure should be maintained between 8-10 

psi (55-69 kPa). Pressure variance between the left 

and right tires can cause an uneven cut.

Lubrication Locations

Lubrication is required at the following locations 

using a lithium complex NLGI #2 grease. Refer to 

the maintenance schedule for service intervals and 

amount of grease.

1.  Rotate the mower deck up to the service position.

2.  Grease the three spindles and the right rear 

roller bearing.

3.  If the mower deck is equipped with a hydraulic 

flip-up kit, grease the flip-up rocker bracket.

4.  Return the deck to the operating position and 

lower to the ground.

5.  Grease the left rear roller bearing, the left and 

right caster wheel pivots, and the left and right 

wheel axles.

6.  Grease the drive shaft bearings and the hitch 

arm pivots. Wipe off any excess grease.
